error if the file-based dloader (e.g., dlopen) fails to load a DSO for
a complex reason (e.g., unresolved symbol).
This has been widely reported upstream to the libltdl maintainers - a
general solution is difficult. This is very definitely an
OMPI-specific solution. Since our embedded libltdl is hidden behind
visibility flags, that's ok.
Note that this is a change to autogen.sh, but this commit does not
force re-running autogen.sh. You'll just get the new functionality
the next time you re-run autogen.sh.
This commit was SVN r22806.
